Do you think it doesn't happen? Sure, not as often forcefully as we see it depicted but if even only 5% of people hitting on girls try to coerce them then that's a lot of people. And considering the (disgusting) rape and sex-crime laws before 2023 it's no wonder the worst guys would try to drag a girl off. (Even while being dragged away a lot of Japanese girls don't want to make a scene by yelling out...)
